The Boondock Saints: Legion

The Boondock Saints: Legion, is a planned third film of the series. In May of 2012 Sean Patrick Flanery confirmed that the third movie was being written. In January 2015 Sean also had an Instagram post titled "Almost Done" with the hashtags 'III' and 'boondocksaints.'

Legion is going to involve the legions of followers who have copied the lead of the Saints. The film picks up with the boys behind bars, just like they were when the second film ended. It will also look into their past, going all the way back to the very first crime they committed
